Oh wow. I'm so sorry that the therapist reacted that way, and didn't talk through what was going on, or even try to understand your feelings. That's terrible.... you deserve better.

In situations like that, I often feel like I don't know what to say (or I just freeze up), because I'm surprised and not expecting what happened. Do you think you might bring it up again, but knowing the therapist's likely response... maybe ask directly for some support or help understanding it?

I'd probably want to ask very direct questions to start the conversation. Like, "can you tell me what types of things you're sharing with this other person?" and "are there any safeguards in place for my privacy?". I'd also ask something like, "Realistically, how exactly am I supposed to be feel safe enough to open up to you, knowing that anything that I say may be passed on to others?"

Stuff like that?

Again, I'm sorry. I'd be freaked out too. The whole point of therapy is to be a private, safe space... a container of sorts. It would feel very very broken and pointless to me.
